If a session is ended, the current transaction in that session will be committed and ended.
All the database changes made in the current transaction will become permanent.
This is called an implicit commit when session is ended. The following tutorial exercise
shows you that the "disconnect" command forces the current transaction to be committed
and ended. When the session is reconnected, you can see the changes made by the UPDATE statements.
